What is the no doxing rule?

Excuse me, could you please clarify what exactly is meant by the "no doxing rule"? I've heard it mentioned in the cryptocurrency community, but I'm not entirely sure of its specific implications. Is it related to the protection of personal information, or does it encompass something broader? And what consequences can arise if this rule is violated? I'm keen to understand the importance of adhering to it within the realm of cryptocurrency and finance.
